Brent Goehring (

PhD Student: Columbia University and in situ 14C Lab Manager

My research focuses on the development and application of new techniques in surface exposure dating, including in situ 14C extraction (link). I am also interested in past and future climate change, combining terrestrial and marine climate proxies, tectonic geomorphology and paleoseismology, and other Quaternary geochronology methods. I have worked in the western United States, Norway, and Greenland.

Meredith Kelly (

Adjunct Associate Research Scientist

My research interests are centered upon investigating the timing and extent of changes in past glacial systems as a means of developing records of global paleoclimate events.  My goal is to use these records to further our understanding of the climate system and causes of abrupt climate changes.


My current research projects target major scientific questions related to the climate system in three different locations.  First, I am developing paleoclimate records from mountain glaciers in Greenland to advance our understanding of seasonality during abrupt cold events.  Second, I am developing records of glaciation in the Peruvian Andes that will help to determine the role of the tropics in the global climate system.  Third, I am determining the timing and rate of deglaciation of the southern sector of the Laurentide Ice Sheet to examine the influence of large ice sheets and melt water on past climate changes.

Irene Schimmelpfennig (

Postdoc Research Scientist


I am interested in refining the cosmogenic nuclide dating method, with focus on production rate calibrations of the in-situ nuclides 36Cl and 14C. Currently, I am setting up the 36Cl extraction procedure from silicates at LDEO and I am running the in-situ 14C lab (link). My research is also centered on Holocene mountain glacier fluctuations in the European Alps using 10Be and in-situ14C (link). In addition, I am involved in projects in Antarctica, Western USA, New Zealand and Patagonia.
